Add CMake configure steps to produce version.h and version.sh from
templates and include the build dir for the generated header. Add
version.h.in and version.sh.in, include version.h in VulkanWidget and
use APP_VK_VERSION for the Vulkan applicationVersion. Update make_deb.sh
to source version.sh for the package version instead
Introduce ScreenLockDetectorBase and move platform logic into
ScreenLockDetectorLinux and ScreenLockDetectorMacOS. Rename mac files to
*_macos, add new base/linux source files, and update CMakeLists to
include them. Convert ScreenLockDetector into a factory/facade that
creates and forwards signals to the platform detector. Add refactoring
docs and a migration guide.
Add RenderWidgetBase and update CustomWidget and VulkanWidget to
implement its interface. Refactor MainWindow to use a single
RenderWidgetBase pointer, unify controls and status UI, and remove the
dual-tab setup. Add design and quickstart docs and register the new
header in CMakeLists.txt.
